Hello all I am new to this forum and have a 1978 XS250. The bike is a runner but difficult to start, It spent 6 weeks in a m/c repair shop having the voltage regulator changed and the carbs sonic cleaned along with some other diagnostic work. Eventually I just collected it as they were unable to find the starting fault and suggested new carbs. The bike it seems at some point had 400 barrels and pistons fitted. The carbs are as far as I can tell still 250 original. I have stripped and cleaned them and had the sonic cleaned but still have starting issues. Since collecting the bike I have spent quite a lot of time myself stripping, cleaning and setting up the carbs, also checking and replacing the plugs and checking the compression which was very good. Is this something you may be able to help with please.

Welcome to the nut house mate, and owning a frigging xs250 you deserve to be in it............

 

 

 

 

 

 

 

Only kidding bud, I'm sure the boys on here will get it sorted. If this forum was about in 1980-82 I probably wouldn't have an inbuilt disgust of the 250......Give us some pics of your Bonnie, go on go on

He did post in the workshop section, committed the grievous forum sin (in my opinion) of copy and paste.

nil points.

Nope, posting an intro question in the workshop and then saying you will go and introduce yourself is fine. Just pasting your original post in my opinion is a bit naff. TBH, if Dirty had seen it even money says it would have been locked.

Just read through this ha I posted in the wrong area by mistake then copied it to the correct area where some members helped me greatly. Am I missing something ?

Its just a pet hate of mine, yours wasn't a biggy as you have hardly got your answer and cleared off. I think an introduction should be just that,

'Hi I'm Bob from the midlands, like customs good with the spanners, just got myself an xs' type of thing.
